This study examines how family farms in Kandi, northern Benin, are affected by rainfall flooding. Data from 80 farmers show that smaller farms are most vulnerable due to limited resources, while larger farms are better equipped to cope. Strengthening education, training, credit access, and cooperative support can help small farmers adapt. The research highlights inequalities in vulnerability and the need for inclusive strategies to improve resilience.

The Lower Ouémé Valley is suitable to rice production thanks to its fertile soils and water resources, though challenged by water management. Two innovative approaches, Smart-Valleys and Intensive Rice Cultivation System, have been implemented to remedy this situation. The combination of these two approaches can improve productivity while conserving water resources. However, their success depends on farmers' ongoing training, access to quality inputs and institutional support.

Proc. IAHS, 388, 9–16, https://doi.org/10.5194/piahs-388-9-2025, 2025
The Lake Nokoué and Porto-Novo Lagoon complex represents the most important Lagoon system in Benin. It Regarding the hydrological regime, a predominance of strictly freshwater taxa was noted during the High water period in Lake Nokoué. Furthermore, this predominance was recorded during both High and Low water periods within the Porto-Novo Lagoon. Thus, the variation of these taxa was found to be more pronounced in Lake Nokoué than in the Porto-Novo Lagoon.

Proc. IAHS, 388, 1–8, https://doi.org/10.5194/piahs-388-1-2025, 2025
Lake Toho is a small freshwater lake located in southern Benin. From February to June 2024, water quality was assessed using monitoring equipment. The results indicate high levels of nutrients that could cause ecological problems such as eutrophication and the disappearance of aquatic species. Market gardening and riverside agriculture are responsible for this pollution.
